feat: add MotherDuck cloud DuckDB support#119
Merged
Conversation
Add a new database provider for MotherDuck, the cloud-hosted DuckDB service. This adds MotherDuck as a separate connection type with its own form fields for database name and access token. - Add MOTHERDUCK to DatabaseType enum - Create motherduck provider with adapter inheriting from DuckDBAdapter - Support md: connection strings with optional database and token - Add unit tests for connection string building and provider registration
- Make database and access token required fields - Use file-based URL parsing for motherduck:///database?token=xxx format - Update tests for new requirements
- Use standard password field (stored in keyring) instead of custom token field - Fix file-based vs tcp-based endpoint handling - Access token is now stored securely via credentials service
MotherDuck requires database.schema.table format for queries. Override build_select_query to include the database prefix.
MotherDuck supports multiple databases, so the explorer tree needs to pass the database name through to build correct queries.
- Rename database field to default_database (stored in options) - This keeps tcp_endpoint.database empty so tree shows Databases folder - Add get_databases() to list all MotherDuck databases - Add get_tables/get_views() with database filtering
